A PA chest radiograph reveals that only seven ribs are seen above the diaphragm on a healthy adult.Which of the following suggestions would improve the inspiration of lungs?

Question

Quizplus · Accepted Answer

Taking the exposure on the second inspiration (rather than the first) will increase the amount of air in the lungs, which will expand the lungs and move the diaphragm down, allowing more rib detail to be seen on the radiograph. Using a higher kV or a shorter exposure time may improve image quality but will not affect lung inspiration. Performing the chest position supine would likely not change the number of visible ribs.
